DUMPING WAGON OR CAR.

To all whom 'it may concern:

Be it known that we, EDWARD C. NORTH and VILLIAM L. KNAPP, citizens ofthe United States, and residents of Palmyra, in the county of Wayne andState of New York, and CHnIsToPHEn H. BIERBAUM, a citizen of the UnitedStates, and resident of Buffalo, in the county of Erie and State of NewYork, have invented a certain new and useful Improvement in DumpingWagons or Cars, of which the following is a specification.

This invention relates to a dumping wagon I or car of that type in whichthe load is carried by rotatable receptacles or trays.

The object of this invention is to produce a dumping wagon or car ofthis character which has a larger capacity and can be arranged lowerthan those heretofore in use and which is so constructed that the loadmay be readily dumped at either side or at the middle of the road overwhich the wagon or car is drawn.

In the accompanying drawings consisting of 2 sheets: Figure 1 is avertical longitudinal section taken in line 11, Fig. 2, and showing ourinvention applied to an ordinary wagon. Fig. 2 is a fragmentary top planview of the same. Fig. 3 is a fragmentary vertical section, on anenlarged scale, taken in line 3-3, Fig. 2. Fig. 4 is a sectional view,on an enlarged scale, taken in line 4-4, 6. 5 is a fragmentaryhorizontal section taken in line 5-5, Fig. 6. Fig. 6 is a fragmentaryfront elevation, on an enlarged scale and partly in section, of ourimproved damp wagon. Fig. 7 is a rear elevation thereof. Fig. 8 is across section, on an enlarged scale,in line 8-8,-Fig. 1. Fig. 9 is a toplan View showing the manner in which tlie trays may be arranged whenthe invention is applied the railway car.

Similar letters of reference indicate corresponding parts throughout theseveral views. v

Our im )rovement may be organized so as to be applicable to wagons andcars in commonuse or the same may be embodied in wagons or cars whichare specially constructed for this purpose.

In 1 to S of the drawings, our improvement is adapted to fit an ordinarywagon the running gear of which consists essentially of front and rearaxles A, A having wheels a, a, a front bolster B arranged above theSpecification of Letters'Patent.

front axle and rovided at o posite ends with upright stalies b, a rearolster C arranged above the rear axle and provided at opposite ends withupright stakes c, a longi tudinal reach D connecting the front bolsterwith the rear bolster and axle and a king pin (1 pivotally connectingthe front bolster and reach with the front. axle. Our improvementapplied to this form of wagon is constructed as follows:

E, E represent a air of standards mount ed on the front bo ster and F, Fa pair of standards mounted on the rear bolster. The standards of eachpair are arranged on opposite sides of the longitudinal center of thewagon and are connected by a transverse bar 9, thereby forming framesfor supporting the movable parts of the dumping apparatus. For thepurpose of holding each pair of stand ards against movement on theirbolster in a direction lengthwise of the wagon each of the standards isprovided at its lower end with a pair of depending checks or flanges hwhich straddle or engage with opposite sides of the bolster.

Between each standard and the ad'acent stake is arranged a horizontalbrace or holder which preferably consists of inner and outer sections 1,I. The Opposing ends of these brace sections overlap each other and areadjustably connected itlreach other by a bolt 'L passing through slots 1in the overlapping parts thereof while their opposite outer and innerends are constructed in the form .of

and standard, respectively. The jaw of the inner section is preferablyconnected with the adjacent standard by-a bolt but the 'aw .of the outersection merely engages rictionally with the stake. By means of theseadjustable braces the frames may be applied to and securely held inplace on the bolsters of wagons in which the distance between the stakesvaries.

vK, K. represent a pair of trays or receptacles which are arrangedtransversely side by side between the front and rear bolsters and whichare adapted to receive the load which is to be. transported. Each ofthese trays is constructed in the form of a segment of a cylinder andconsists of a transversely curved body Z forming the side walls andbottom of the tray and vertical walls I, 1 arranged at opposite ends ofthe body. These trays are rotatable about horizontal parallel axes sothat the opening of the same may be turned upwardly for receiving theload or turned down ardly for discharging the load. For this purpose thefront and rear end walls of each tray are provided on their outer sideswith 'trunnions m, m which are arranged axially 1n hue and which arejournaled re- I bodies engage each other at a point horizontally inlinewith the axes of both trays while their outer edges ext-end above saidaxes. When both trays are filled the heap of material extends over theinner edges of the Samoa-11d as the heap of material is usually higherat the middle than at the sides a greater amount of the same iscontained within, the inner portions of the trays than in the outerportions thereof. In order to compensate for this difference thetrunnions of each tray are placed a sullicient distance" inwardlyrelatively to the point or center]; from which the body of the tray isdescribed to balance the weight of the material within the tray onopposite sides of the center about which it rotates, as most clearlyshown in Figs. 7 and 8. By this means the devices which hold the traysin place are relieved from undue strain and it also enables theattendant to easily dump the load and reliably control the same.

When it is desired to dump the load in the trays along the middle of theroad over which the wagon is moving the same are turned sot-hat theinner longitudinal sides or edges thereof are depressed. And if it isdesired to dump the trays along the side of the road over which thewagon 1s traveling the same are turned so that the outer longitudinalsides of the same are depressed.

In order to permit of carrying the end walls upwardly a sufficientdistance to conthe inner portions 0 of the edges of these end wallsdiverge upwardly from the meeting line at the inner longitudinal sidesof the bodies. The edges 0 are preferably curved concentrically with theaxes of the trays, as shown best in Fig. 8, and the spaces between thesecurved edges of each pair of companion end walls is closed by an uprightshutter or bridge plate P.

\Vhen dumping the trays inwardly the material is prevented from lodgingon the reach of the wagon by means of a deflector which preferablyconsists of two inclined or curved plates (1, g arranged lengthwiseabove the reach and between the trays and diverging from their upperconnected ends downwardly beyond the opposite sides of the reach. Thesedeflecting plates are preferably secnred at opposite ends to the frontand rear cross bars of the standards so that they are immovable and thelower ends of the shutter plates P, are secured to opposite ends of thedeflector, as shown in the draw- 111 s.

Various means maybe provided for ermitting the trays to besimultaneously umped either inwardly or outwardly or to permit each trayto be dumped inwardly or outwardly independently of the other tray. Themeans for this purpose shown in the drawings, as an example, areconstructed as follows: It represents a horizontal operating shaftarranged transversely above the front trunnions of both trays andprovided near opposite ends with two worms r which mesh with worm-wheelss on said front trunnions. These worms and their cooperating wormwheelshave their threads and teeth trending in opposite directions so thatwhen the shaft R is turned in one direction both trays will be depressedon their inner sides for discharging the load along the middle of theroad while upon turning the shaft in the other direction the trays willbe depressed at their outer sides for discharging the load along theside of the road. Any suitable means may be employed for operating thisshaft, that shown in the drawings being suitable for this purpose andconsisting of a ratchet wheel T secured to the central portion of theshaft, a rocking hand lever t mounted loosely on the shaft adjacent tothe ratchet wheel, a )awl pivoted on the hand lever and having rent andrear dogs or teeth a, u projecting from opposite sides of its pivot andan n wardly rojecting lug u arranged centrally etween its teeth, and aspring '0 arranged between said lug and an abutment v on the hand leverand 0 rating to hold either of said dogs or teet 1 yieldingly inengagement with the teeth of the ratchet wheel. As shown in 55 fine theload against spilling from the trays Fig. 4, the front tooth of the pawlis in en- 3 at the front and rear ends thereof and still ga'gement withthe ratchet wheel and upon permit the trays to turn freely downwardlyreciprocating the hand lever while the pawl on their inner sidesrelatively to each other isin this osition the shaft will be turned inthe directlon of the arrow Fig. 4. The pawl is thus held with its fronttooth in engagement with. the teeth of the ratchet wheel by reason ofthe connection between the lug u and spring 12 being in front of thedead center between the pivot of the pawl and the abutment '0. Uponshifting the pawl by hand 1 0 areas? so that the point of connectionbetween the lug u and t e spring rv is in rear of the dead center, therear tooth of the pawl will engage the ratchet wheel and cause the shaftto be turned intermittently in the opposite direction upon rocking thehand lever.

It is sometimes desirable to dump the contents of only one of the trayseither at the middle or at the side of the roadway while the contents ofthe other tray are not disturbed, this being the case where uniformdistribution or grading of the material is required. To permit of this,means are provided for disconnecting either of the trays from theturning device. The preferred means for this purposewhich are best shownin Figs. 1, 2, 3 and 6, consist of two rotating cams or eccentrics Wjournaled loosely at opposite ends of the operating shaft and eachengaging on its upper and ower sides with laterally projecting abutmentsor lugs w, w formed on a bracket X on the outer side of the adjacentstandard. U on turning one of these eccentrics in one (irection, therespective end of the shaft carried thereby is raised and thecorresponding worm is disengaged from -the companion worm-wheel while uon turning the eccentric in the o osite irection said end of the shaftwill 0 owered and the corresponding worm will be engaged with itsworm-wheel. When one of the worms is thus lifted out of engagement fromits wormwheel the corresponding tray will be unaffected by the rotationof the shaft while dumping the other tray. It will be observed that b'ythis means the contents of either tray can be discharged at will, thuspermitting of greater uniformity in the distribution of the material. Uon raising and lowerin the ends of the she t the same are guided invertical slots at in the brackets which receive those ortions of theshaft between the worms and the eccentrics.

While either one of the trays is uncou led from the turning mechanismthe same is held in place by means of a locking device which ispreferably. so constructed that the lockin of the tray is effectedautomaticall and s1- multaneously upon disengaging t 0 same from theturning mechanism. As shown in Figs. 2, 3, and 6, the turning of eacheccentric is effected by means of a handle or rock arm 'y arranged onthe outer side of the same. This handle projects upwardly when thecorres onding worm is in its 0 )erative position am downwardly when saidworm is in its inoperative position. On its front side each eccentricarm is provided with a tooth y and each tray is rovided on the outerside of its front wall with a segmental row of teeth y forming a toothedrack which is arranged concentrically with the axis of rotation of therespective tray. When the worm and wormwheel of one tray are in mesh andthe corresponding eccentric arm projects upwardly the tooth on thelatter is disengaged from the teeth on the adjacent tray permitting thistray to be turned. But when the eccentric arm is moved downwardly anddisengages the respective worm-wheel and worm, the tooth of said arm enages between two teeth of the rack and ho ds the respective tray againstturning. By providing a segmental row of these teeth for each tray it ispossible to uncouple the same from the turning mechanism and hold thetray against accidental displacement either in its normal filledposition or in its abnormal or partly dumped position.

By employing two trays side by side for supporting the load a greateramount of material can be carried in a wagon of given dimensions, a muchstronger structure is produced owing to the division of the load etweenthe two trays, the wear upon the arts is reduced and the weight of theload 18 better distributed.

Furthermore this construction of dumping wagon permits of carrying theload nearer the ground which reduces the danger of tipping and alsoermits of dum in the load either at the middle or at the si e o theroad, thereby reducing the amount of labor for subsequently rading orevening up the material after it is dumped.

It will be observed that all of the devices whereby the trays aremanipulated are arranged within convenient reach of the drivers seat zwhich is mounted on the front of the wagon enablinghim to maintaincontrol of the horses and attend to the dumping mechanism withoutleaving the seat.

When our improved dumping device is used on railway cars two or morepairs of such rotary trays may be mounted on the same car and operatedby mechanism constructed substantially like that shown in Figs. 1, 2, 3,4 and 6. As shown in Fig. 9, two pairs of such trays K, K arerepresented as mounted and to end on a car platform K.

It is obvious that our improved (lumping mechanism is applicable towagons as ordinarilv constructed as well as to wagons whic may beespecially constructed to remeive our improvements.
